3 Warranty
Warranty and technical assistance
Munters products are designed and built to provide reliable and satisfactory performance but cannot be
guaranteed free of faults; although they are reliable products they can develop unforeseeable defects and the user
must take this into account and arrange adequate emergency or alarm systems if failure to operate could cause
damage to the articles for which the Munters plant was required: if this is not done, the user is fully responsible for
the damage which they could suffer.
Munters extends this limited warranty to the first purchaser and guarantees its products to be free from defects
originating in manufacture or materials for one year from the date of delivery, provided that suitable transport,
storage, installation and maintenance terms are complied with. The warranty does not apply if the products have
been repaired without express authorisation from Munters, or repaired in such a way that, in Munters’ judgement,
their performance and reliability have been impaired, or incorrectly installed, or subjected to improper use. The user
accepts total responsibility for incorrect use of the products.
The warranty on products from outside suppliers fitted to the Repeater, (for example cables, etc.) is limited to the
conditions stated by the supplier: all claims must be made in writing within eight days of the discovery of the defect
and within 12 months of the delivery of the defective product. Munters has thirty days from the date of receipt in
which to take action, and has the right to examine the product at the customer’s premises or at its own plant
(carriage cost to be borne by the customer).
Munters at its sole discretion has the option of replacing or repairing, free of charge, products which it considers
defective, and will arrange for their despatch back to the customer carriage paid. In the case of faulty parts of
small commercial value which are widely available (such as bolts, etc.) for urgent despatch, where the cost of
carriage would exceed the value of the parts, Munters may authorise the customer exclusively to purchase the
replacement parts locally; Munters will reimburse the value of the product at its cost price.
Munters will not be liable for costs incurred in demounting the defective part, or the time required to travel to site and
the associated travel costs. No agent, employee or dealer is authorised to give any further guarantees or to accept
any other liability on Munters’ behalf in connection with other Munters products, except in writing with the signature
of one of the Company’s Managers.
